Abstract

Nonpoint source pollution has been found to be a widespread and serious problem in the Metropolitan Twin Cities Area, Minnesota. The runoff monitoring program consisted of precipitation, runoff, and water quality data collection at 17 sites. Subsequent statistical modeling allowed for projection of this data in time and space over the entire Region. A concurrent lakes sampling program was conducted on 60 lakes in the Region to assess the nature of runoff impact on lakes. Snowmelt was found to be a very significant contributor to annual pollutant loading.
